Halloween costumes are expensive. You blink at the price tag, and suddenly you’re wondering if you should’ve just stayed home with a bag of candy instead. But here’s the thing: you don’t need to drop half your paycheck to look like you walked straight out of a costume shop. DIY trendy Halloween costumes can look ridiculously professional with just a little creativity (and maybe a hot glue gun or two).
I’ve tried both ends of the spectrum—the overpriced “instant regret” store-bought outfit and the “let’s wing it” DIY attempt. And guess what? Nine times out of ten, the DIY one got way more compliments. Plus, nothing feels better than someone asking, “Wait, you MADE that?!” So, if you want a killer costume this year without the terrifying receipt, here are 10 DIY trendy Halloween costumes that look store-bought but cost way less.
1. Barbie (Because She’s Literally Everywhere Right Now)
Thanks to the Barbie movie, pink has officially become the new black. You can pull this one off without much effort.
- Grab anything hot pink in your closet—think dresses, matching sets, or even a pink blazer.
- Add oversized sunglasses and chunky heels.
- Accessorize with a plastic hairbrush, roller skates, or a Barbie box frame (DIY with cardboard).
Why it works: The Barbie aesthetic screams “put together,” but it’s literally just your pink clothes with a side of confidence. Ever noticed how Barbie never worries about clashing colors? Neither should you.
2. Wednesday Addams (Because Moody Chic Never Dies)
If you already live in black clothes, congrats—you’re halfway there.
- Black collared dress (or black dress with a white collared shirt layered underneath).
- Two braids, pale makeup, and a deadpan expression.
- Bonus points if you carry a headless doll or a fake crow.
Pro tip: Don’t smile. Ever. People will instantly get it. And honestly, it’s the easiest excuse to avoid small talk at parties.
3. The “Eras Tour” Swiftie
Taylor Swift basically invented themed wardrobes at this point. Channeling her on Halloween? Easy.
- Pick your favorite “era” (Red = heart-shaped glasses + scarf, Reputation = black bodysuit + bold eyeliner).
- Add glitter, sequins, or cowboy boots.
- Carry a toy microphone or a friendship bracelet stack.
Why people love it: Everyone knows at least one Swiftie, so this costume gets instant recognition. IMO, it’s one of the most fun DIY Halloween costumes because you get to play dress-up in multiple vibes.
4. Classic Witch With a Modern Twist
The witch never goes out of style—but 2025 witches aren’t wearing floppy Party City hats.
- Black slip dress or sleek jumpsuit.
- Tall boots and dramatic dark lipstick.
- DIY witch hat with fabric scraps or wire (make it chic, not floppy).
- Add sparkly accessories for a “glam witch” effect.
Ever noticed how witches always steal the spotlight? It’s because the look screams power. So yes, you’ll look like you bought it from a boutique costume store when really you raided your closet.
5. Ghostface (But Make It Trendy)
You don’t need to buy the whole kit. Ghostface can totally go high-fashion.
- Black hoodie and jeans (instead of the full cloak).
- Add the Ghostface mask (cheap at any store).
- Accessorize with fake blood or even a coffee cup for a “lazy killer” vibe.

Pro tip: If you want to stand out, skip the plastic robe that everyone else wears. Pair the mask with everyday clothes—it looks even creepier. Seriously, imagine Ghostface showing up in ripped skinny jeans. Terrifying and stylish.
6. Cowboy Chic (Because Western Is Back)
Thanks to Beyoncé’s “Cowboy Carter” era, western fits are in again.
- Plaid shirt or denim jacket.
- Cowboy hat (you can DIY one with cardboard if you’re crafty).
- Boots and a belt with a big buckle.

- Optional: Lasso made from a rope you probably already own.
This one looks like a costume, but it’s basically an excuse to wear trendy western streetwear. And FYI, this one doubles as a legit outfit for the bar after Halloween. Win-win.
7. Pop Culture Meme Costumes
Who says costumes have to be serious? Memes make for hilarious DIY fits.
Ideas that scream “trendy”:
- “Girl Math”: Carry a calculator and wear a money sign tee.
- NPC TikTok: Dress in neutral colors, repeat robotic phrases, carry a fake joystick.
- “Girl Dinner”: Walk around with a plate of cheese cubes and crackers.
The best part? These look thrown together but actually read as clever. People love a costume that makes them laugh more than a generic vampire.
8. 2000s Y2K Nostalgia
The early 2000s are back, and Halloween is the perfect excuse to live your Paris Hilton fantasy.
- Low-rise jeans (bonus if they’re bedazzled).
- Baby tee or rhinestone tank top.
- Flip phone (fake or real) and oversized sunglasses.
- Tiny purse.
Why it slaps: Everyone loves nostalgia. You’ll look like you bought your outfit at a costume shop, but really you just raided your mom’s attic (or thrift store). ;)
9. Social Media “Filter” Costume
This one’s low-effort but surprisingly genius.
- Print out Snapchat/Instagram filter frames (DIY with cardboard or poster board).
- Hold it up as a frame around your face.
- Dress to match the vibe of the filter (dog ears, flower crown, glam makeup).
It’s interactive, fun, and looks like a legit creative costume you bought online. Ever noticed people love taking selfies with these? Yeah, you’ll be everyone’s favorite party stop.
10. Greek God/Goddess
Okay, hear me out—bedsheets. But not the sloppy college toga-party version.
- Use a white bedsheet, but pin/tuck it properly for a draped effect.
- Add a belt or gold cord for structure.
- Accessorize with DIY gold leaves (spray-paint some real leaves if you’re extra).
- Sandals complete the look.
It looks like a costume store rental but literally costs you $0 if you already own the sheet. And people always hype up a well-done Greek costume.
Bonus Tips to Nail the DIY Look
Want your DIY costume to look even more store-bought? Keep these tricks up your sleeve:
- Invest in makeup: Good makeup sells any costume. A smoky eye or glitter detail can elevate even the simplest look.
- Accessorize smartly: Small props make a huge difference. Think fake blood, wigs, sunglasses, or jewelry.
- Fit is everything: Even the cheapest DIY looks expensive if it fits you well. Tailor with safety pins if needed.
- Confidence sells: If you wear it like you meant it, nobody questions it. Ever noticed how people rock the wildest outfits at fashion week? Same rule applies here.
